Given numbers are 678,816,492,285

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 678,816,492,285 is 359150160.

Find LCM of 678,816,492,285 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 3 x 113 x 68 x 41 x 95 = 359150160

Therefore, the lowest common multiple of 678,816,492,285 is 359150160.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

678 x 816 x 492 x 285 = 77576434560

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

678 : 1, 2, 3, 6, 113, 226, 339, 678

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

285 : 1, 3, 5, 15, 19, 57, 95, 285

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,816,492,285, is 3.

Now, the common factors can be found like this.

678:2x 3x 113

816:2x 2x 2x 2x 3x 17

492:2x 2x 3x 41

285:3x 5x 19

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 3x 3 = 72

Therefore, the value for common factors is 72.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 77576434560/(3x72)

LCM = 77576434560/216

LCM = 359150160

Thus, we can understand that the LCM of 678,816,492,285 is 359150160.
